Asynchronous commu

In telecommunications, asynchronous communication is transmission of data without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream. Any timing required to recover data from the communication symbols is
encoded within the symbols. The most significant aspect of asynchronous
communications is variable bit rate, or that the transmitter and
receiver clock generators do not have to be exactly synchronized.
